RESUMEN
OBJECTIVE: The aim of this study was to compare uroflow parameters of patients with pure constipation against those with constipation plus lower urinary tract symptoms (LUTS) and a control group (no constipation). MATERIALS AND METHODS: During August 2012 to March 2014 three groups of patients were enrolled into the study: group C (constipation only), group CL (LUTS plus constipation) and group N (control: no constipation or LUTS). Dysfunctional elimination syndrome (DES) scores, uroflowmetry/electromyography (uroflow-EMG) findings, postvoiding residual urine (PVR) and rectal diameter were measured and compared between groups. RESULTS: Groups C, CL and N comprised 80, 100 and 30 patients, respectively. Average DES scores were 12.6, 18.7 and 4.9, respectively. Voided volume (as a percentage of expected bladder capacity) was 104%, 89% and 101%; and average maximum flow rate was 21.1 ml/s, 36.4 ml/s and 28.1 ml/s, respectively. Pelvic floor muscle activity during voiding was seen in 40.0%, 42.0% and 6.7% of patients in groups C, CL and N, respectively; and pathological PVR was seen in 26.3%, 55.0% and 3.3% of patients in the respective groups. Average rectal diameter was measured as 38.6 mm, 36.4 mm and 28.1 mm in groups C, CL and N, respectively. CONCLUSION: This study found that abnormal voiding parameters are present in patients with constipation even if LUTS are not present. Therefore, it is important that all patients presenting with constipation have their voiding function evaluated.
RESUMEN
OBJECTIVE: To evaluate and compare the effectiveness of biofeedback therapy (BF) in children with treatment refractory overactive bladder (OAB) and dysfunctional voiding (DV). METHODS: This study was performed between April 2012 and March 2014. Patients with treatment refractory OAB and DV were included. All patients had 3 months of BF. Patients' urologic system symptoms and uroflow parameters before BF and 3 months after BF and response rates were compared. RESULTS: Forty-five patients completed the study. Significant improvement was seen in urinary tract infections, urge incontinence, fractionated voiding, constipation, voided volume, maximum flow rate (Qmax), average flow rate (Qave), and postvoiding residue for patients with DV and in urinary tract infection, frequency, urge incontinence, Qmax, Qave, voiding time, and postvoiding residue for patients with OAB. Overall, better results were observed in patients with DV. CONCLUSION: BF is an effective treatment modality in children with treatment refractory OAB and DV; however, patients with DV show better improvement.
